The High School Study Ascertaining And Analysis Of The Cause Of Formation Of The Chemical Fuzzy Concepts Under The New Curriculum

The science learning shows that ,the influence of the student chemistry study ,one of the important factor is the chemical fuzzy concept which in the student's minds.The chemical fuzzy concept is inconsistent with scientific explation in the process of learning.The chemical fuzzy concepts have a lot of negative impact on the student's chemistry study and impact their continue learning.The chemical fuzzy concepts hinder the students from the well cognitive structure .The chemical fuzzy concepts'formation is relation with that the student have incomprehension on the chemical concepts.The chemical fuzzy concept in high school students'minds is objective existence.From the perspective of the development of human knowledge,chemical fuzzy concept is normal, also inevitable.The imformation of the fuzzy concepts in the student'minds is consistent with the human's cognitive process,is also from low lever to high lever,from simpleness to complexity ,from fuzzy to correct.By means of the researching ,we discover that the chemical fuzzy concepts in the students'mind is die-hard,pervasiveness and universality.The innovation of the article has used two-tier, the merit of the two-tier is convenient, easy,save effort, carry on the investigation easily.The first part of the paper expound the background and meaning of the research of the chemical fuzzy concepts .The author side that ,by meanings of the research of the chemical fuzzy concepts could help the students to form the well cognitive structure and scientific chemical concept.And it could help the teacher to change their teaching fashion.The second part of the paper expound the theory of the research of the fuzzy concepts.The author analyzes the fuzzy concepts in the students minds from the construction principle study theory and the Conceptual Change Theory.We should take the fuzzy concept as one can be converted congnitive structure .We should make full use of our practical experience and theoretical basis , and teaching art to remove the fuzzy concepts than in the students'minds.We also should transmit the correct concepts to the students. This topic research for teaching practice has very important practical significance.The third part of the paper is under the guidance of Constructivism learning theory and the Concept transformation theory , combine with the character of Science education,take the senior high school teaching material of chemistry Required Course I (People's education press)as carrier, make a preliminary inquiry on the students'fuzzy chemcial concepts.By meanings of the Two-tier test and interview method to diagnose and analyse the existent of the fuzzy chemical concepts which in the students'minds. And we anlyse the reasonfor the fuzzy concepts and the character of the fuzzy chemical concepts,and the impact on the students'study.And the author give some suggestion to change the Chemical fuzzy concept.The last part is the conclusion of the thesis.
